Well, the question that I have is whether the character length
determination trick is a show-stopper for you. I think that knowing that
might help people make up their minds, assuming anyone else is even
noticing this discussion. I like US-ASCII myself, from a programmer's point
of view, but I can see several factors that argue against it:

    + FFFE is already established in Unicode, so many multi-byte systems
will have text-editors that can deal with the initial FFFE.

    + Generic text-editing tools will almost certainly turn the user's view
of a US-ASCII header into garbage on multibyte systems, but would not turn
ISO character codes <127 into garbage.

    + Many people will want to edit XML with generic text-editors on their
systems in their native character codes.

    Given the foregoing, the loss of elegance might pay off in a real gain
in utility. An XML parser could even just cast the characters read into 8
bits to use a legacy HTTP header parser. So even the programmer isn't too

Notice that with a MIME-header we also get a convenient place to specify an
XML version, and anything else we might need.

I can agree with Gavin that catalogs are more elegant, but in some contexts
they may not be more convenient. And as Tim and Michael note, a header that
is integral is less likely to be lost...
